Description
Technical field
This utility model relates to electronics electric control field, is specifically related to electricity system under a kind of automobile electric control unit time delay.
Background technology
The electromotor that automobile electric control unit is widely used in automobile as the controlling organization of executor controls, and motor controls, and change speed gear box and gearshift control, the field such as oil pump and vacuum pump control.Generally under vehicle after electricity (closedown of vehicle wake-up signal), it is still desirable to ECU performs certain action, running state information and fault message are write nonvolatile storage by such as ECU；Or gearbox-gear is return neutral etc. by controlling lock unit by gear box electrical control unit, after completing above action, just requires that ECU is out of service.
Under automobile electric control unit time delay at present, Electricity Functional mainly uses to increase special energy-storage system, relay or increase special delay circuit outside ECU and realizes.Using energy-storage system, the ECU delay working time after vehicle wake-up signal is closed is restricted by energy storage system capacity, it is impossible to the arbitrarily regulation lower electricity time；Using relay to add the volume of ECU, the lower electricity time that controller is actual simultaneously relatively descends the signal of telecommunication to there is the delayed of certain time, and the opening and closing number of times of relay contact itself limits the service life of ECU；Outside ECU, increase special delay circuit, add extra hardware cost, too increase the complexity of ECU external electrical system.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of and can realize the lower electricity circuit of Electricity Functional under time delay according to ECU internal component, the volume of ECU can not be increased, also reduce and realize the hardware cost of Electricity Functional under ECU time delay.
For reaching above-mentioned utility model purpose, electricity circuit under a kind of automobile electric control unit time delay is provided, including low-voltage power supply system, vehicle wake-up signal interface and ECU, described low-voltage power supply system is connected with ECU with vehicle wake-up signal interface, and ECU includes having the enable power supply chip of pin, ECU microcontroller and the delay unit being made up of resistance, audion；The input of described power supply chip is connected with low-voltage power supply system, and the outfan of power supply chip connects microcontroller；Described vehicle wake-up signal interface connects delay unit input, and delay unit outfan connects the anode of diode D1, and the negative electrode of diode D1 is connected with the negative electrode enabling pin and diode D2 of power supply chip, and the anode of diode D2 is connected with microcontroller.
Preferably, described delay unit includes six resistance and two audions, and resistance R1 one end connects vehicle wake-up signal interface, the base stage of other end connecting triode Q1 and one end of resistance R2, resistance R2 other end ground connection；The grounded emitter of audion Q1, colelctor electrode is connected with resistance R4 one end；The base stage of resistance R4 other end connecting triode Q2 and one end of resistance R3, the other end of resistance R3 is connected with the low-voltage power supply system introducing ECU；The colelctor electrode of audion Q2 is connected with the low-voltage power supply system introducing ECU, and emitter stage is connected with one end of resistance R5, and the other end of resistance R5 is connected with the other end of diode D1 and resistance R6, the other end ground connection of resistance R6.
This utility model is incorporated into the vehicle wake-up signal within ECU when being high level, by controlling the conducting of audion Q1, thus realize controlling the conducting of audion Q2, and then make the low-voltage power supply within introducing ECU through the dividing potential drop of resistance R5 and R6, by diode D1 on-load voltage on the enable pin of power supply chip, make power supply chip work and export the voltage that microcontroller can be made to work, start working after the voltage that microcontroller input is exported by power supply chip, and by the diode D2 enable pin output voltage to power supply chip；After under vehicle, electric car wake-up signal interface is closed, audion Q1 ends, thus audion Q2 cut-off, the low-voltage power supply being incorporated into ECU cannot be made to be carried on the enable pin of power supply chip by dividing potential drop, but it is because microcontroller still through diode D2 to the enable pin output voltage of power supply chip, make power supply chip continuous firing and persistently can export the voltage making microcontroller work, and then microcontroller continuous firing, ECU continuous service performs action to be performed in electric process under time delay；When action completes to need ECU out of service, microcontroller stops the enable pin output voltage to power supply chip, and power supply chip quits work, and microcontroller quits work, and ECU is out of service.
